I agree, but I think that you seriously underestimate the cost of such a device. To do what you just described, you need a pair of three axis accelerometers (alone more than the total cost for a basic alpine ski binding) plus strain sensors in multiple axes on each binding. The embedded, weatherproof circuit that can integrate the data from the accelerometers and strain gauges to make the decisions to release toe and heel lugs is also relatively cheap, but still more expensive than an entire basic ski binding. You wouldn't be able to use very much off the shelf hardware at all; very cold and wet environments subject to large magnitude vibration and impact are not common places to put relatively complex electronics.
Then there is the pesky power requirement. You need at least four solenoids or latches of some sort to keep the toe and heel lugs closed. One would think you'd want it normally unlocked to prerelease in case of system failure. You need to package a battery that will last through at least one ten hour day at -20, and I'm guessing its going to be a bit bigger and heavier than a cellphone battery.
Adidas' shoe is incredibly simple in comparison; also there is little doubt that Adidas could afford to lose money on a halo shoe as a marketing cost. Despite this, Adidas' incredibly simple shoe costs four times as much as the retail cost of a basic ski binding.
Lastly, this binding would have to satisfy industry standards, which would mean changes to current standards. I'll bet that is expensive
. Then there are the liability risks inherent in doing something new...
|If Adidas can make running shoes that electronically adjust servos to adapt to every foot step you make than a binding like this should be cake.
Go for it, I'd love to see a prototype.
BTW, a prototype has been made and linked on Epic before.
